MANIFOLD-HEATER.

Specification of Letters Patent.

Patented Nov. 16, 1920.

To all whom it may concern Be it known that we, HARRY D. WORK- MAN andl/VILLIAM S. SMITH, citizens of the United States, residing atTishomingo, in the county of Johnston and State of Oklahoma, haveinvented certain new and useful Improvements in Manifold-Heaters, ofwhich the following is a specification.

This invention relates to a manifold heater for internal combustionengines, and an object of the invention is to provide a device forheating the intake manifold of an internal combustion engine tofacilitate the vaporizing of the combustible fuel being fed into thecylinders of the engine, so as to permit the engine to be started in allkinds of Weather, as well as to cause quick and thorough vaporization ofthe fuel resulting in the obtaining of the maximum power therefrom.

Another object of the invention is to pro vide a manifold heater asspecified which heater comprises a pipe section adapted to be clamped inengagement'with a manifold to the lower end of which section a lampstructure is detachably connected, the said lamp structure havingcommunication with the interior of the pipe section, so that the heatgenerated by the flame in the lamp will heat the manifold of an internalcombustion engine. A further object of the invention is to provide meansfor igniting the wick in the lamp structure, which means may becontrolled from the. instrument board of an ordinary motor vehicle, andwhich comprises a pivoted lever carrying a Dyrophoric wheel which isdrawn over asparking member, to ignite the wick, and to connect thelever which carries the pyrophoric wheel to a lid or cover of the lampstructure, which will, when the control is released fall and close theupper outlet of the lamp, snutfing out the flame on the wick, while whenthe cover is raised by operation of the control, the pyrophoric wheelwill be moved over the washer, to-ignite the wick.

Other objects of the invention will appear in the following detaileddescription taken in connection with theaccompanying draw: ings forminga part of this specification and in which drawings: v

Referring more particularly to the drawings, wherein like charactersindicate like and corresponding partsv throughout the several views, Aindicates a motor vehicle of any approved type having the usual motor orinternal combustion engine B therein and instrument board C. Theimproved manifold heater 10 is attached to the intake manifold D of theengine B and is provided for heating the fuel delivered into thecylinders of the engine from the carbu'reter through the intake manifoldD.

The improved manifold heater 10 comprises a substantially T-shaped pipeor conductor 11, the cross head or portion of which, is substantiallysemi-cylindrical in shape, being opened at its fiat side, and providedwith spaced flanges 12, which engage the outer surface of the manifold Das clearly shown in Figs. 3 and 7 of the drawings. The stem or dependingportion of the T-shaped pipe 10 is also cut away for a portion of, itslength as shown at 14, provided with flanges 15,similar to the flangesI2 for engaging against part of the depending portions of the intakemanifold D. The stem 13 is bent outwardly, below the cutaway portion asclearly shown in Fig. 3 and is flattened to assume substantially arectangular shape, having its lower end open. A pair of spring catches16 are carried by the rectangular portion 17 of the T-pipe 10 and theyare provided for engagement over lugs 18 formed upon the sides or edgesof'a lamp housing 19. This lamp housing 19 is ectangularshaped in crosssection and fits into the lower 0 en end of the rectangular portion 17.The lamp structure 19 includes a wick 20 which passes upwardly to apartition 21 in the lamp housing and is arranged so that flame from thewick will pass upwardly into the pipe 10 for heating the manifold D. Theportion of the housing 19 below the partition 20 is filled with anydesired fuel, through a suitable filler opening 22. The wick 20 isignited, by means of an igniter structure comprising an articulated arm23 carrying a wheel 24 of suitable pyrophoric material upon its freeend, which is adapted for engagement with an abrader 25 to cause sparksto ignite the wick and fuel therein. The abrader 25 is yieldably held bymeans of a spring in engagement with the periphery of the wheel 24.

The articulated arm 23 is pivotally connected to a cover 26 on the upperend of the lamp housing 19 and when this cover which is hingedlyconnected to the housing 19 is lowered it will smother the flame of thewick, putting it out. However, when the cover 26 is raised or moved intoan open position it will move the wheel 24 over the abrader 25 to causea spark for igniting the wick 20. The stem 13 is provided with aplurality of vent openings 27 to permit the supplying of the necessaryair to the interior of the stem and the lamp housing to allow the fuelin the wick to burn.

A wire 28 is connected to the cover 26, and extends through a suitableprotector 29 of the flexible shaft type, to the instrument board C ofthe motor vehicle, and it extends through a slot 30 in the saidinstrument board, having its end remote from the cover 26 attached to asuitable button 31. The button 31 is provided with a recess 32 therein,which is adapted to receive the angled end 33 of a spring lock member34:, to hold the button in an extended position relative to theinstrument board 0, and when in such position to hold the cover 26 opento allow the lamp to burn, to heat the manifold D. Then the button 31 ismoved inwardly toward the instrument board C, the cover 26 will beclosed, for putting out the lamp. The slot 30 will permit oscillatorymovement of the button 31, to move it sufliciently to disengage theangled end 33 from the re cess or notch 32. The T-shaped pipe oftheheater is clamped to the manifold D by split ring clamps 35 and theedges of the flanges 12 and 15 bind against the manifold for preventingto a material extent the escape of the heated air from within the pipesection 10, resulting in the air which is heated by the lamp structure19 heating the manifold D and through the manifold l.) heating the fuelfel l into the cylinders of the engine B, to facilitate the vaporizingthereof so as to permit the fuel to be readily exploded within thecylinder regardless of weather conditions and also to permit morethorough vaporizing of the fuel and conse- "P P stantially semi-circularand havlng its fiat quent obtaining of the maximum power efficiencytherefrom.
